Doubts Arise Over Death Sentence for Missouri Man.

Six jurors who sentenced Michael Tisius to death in 2010 for killing two guards during a jailbreak attempt have signed affidavits supporting a commutation of his sentence to life imprisonment. The jurors cited Tisius' difficult childhood, mental impairments, and good behavior in prison since his conviction as reasons for their change of heart. Tisius' execution is scheduled for Tuesday, but his legal team has filed a clemency petition with Missouri Gov. Mike Parson. The case highlights the emotional toll that the death penalty can take on jurors and others involved in the process.
